This is actually an idea I had years ago but just remembered
when I was thinking about pizza.

Trying to reach a friend who didn't have a phone, I stopped
at
a Western Union office and priced sending a message
($10.00).
Too pricy, I declined and hit upon this idea.

I called the local
Pizza Parlor in my friend's town and
ordered a hot cheese pizza to be delivered. "By the way," I
asked, "Could you write on the box 'will not arrive until 10
pm. [name]"? Voila! Message sent in fifteen minutes with a
hot cheese pizza thrown in extra.
